Hyper-V has an abstract bus, which gets renumbered on guest
startup. So instead of the bus numbers we should be using
the device GUIDs, which can be retrieved from the 'device_id'
sysfs attribute.
This was documented in the man page and supported in the generator,
but systemd-cryptestup itself would fail with this option.
systemd-cryptsetup should ignore 'nofail', as it does with 'noauto'.
This adds #ifdef HAVE_ATTR_XATTR_H guards around all usage of xattr.
This unbreaks building with --disable-xattr when <attr/xattr.h> doesn't exist.
<attr/xattr.h> and usage of fsetxattr() without
This introduces a new data threshold setting for sd_journal objects
which controls the maximum size of objects to decompress. This is
relieves the library from having to decompress full data objects even
if a client program is only interested in the initial part of them.
This speeds up "systemd-coredumpctl" drastically when invoked without
parameters.
[Tested in latest gnome-ostree; if accepted, I'll look at a followup
patch which fixes the other dbus_connection_send(reply, ...) calls
besides logind]
DBus messages can have a flag NO_REPLY associated that means "I don't
need a reply". This is for efficiency reasons - for one-off requests
that can't return an error, etc.
However, it's up to users to manually check
dbus_message_get_no_reply() from a message. libdbus will happily send
out a reply if you don't.
Unfortunately, doing so is not just less efficient - it also triggers
a security error, for complex reasons. This is something that will
eventually be fixed in dbus, but it's also correct to handle it in
client applications.
This new helper API is slightly nicer in that you don't have to pass
NULL to say you don't want a reply serial for your reply.
This patch also tweaks logind to use the API - there are more areas of
the code that need this treatment too.
strncmp() could be used with size bigger then the size of the string,
because MAX was used instead of MIN.
If failing, print just the offending mount flag.
Whenever a message fails, mention the offending word, instead
of just giving the whole line. If one bad word causes just this
word to be rejected, print only the word. If one bad word causes
the whole line to be rejected, print the whole line too.

Sometimes it is better to see messages in full, and the existing
set of options didn't allow this easily. E.g. now
journalctl -f --full
will behave like
tail -f /var/log/messages
of yore.
Long option only for now, since small letters are becoming
scarce, and this doesn't feel like a capital-letter-option.
'-u' would be nice, and the above command would be spelled
journalctl -fu
The path doesn't change in the standard configuration.
Also, give full path to the journalctl binary in the hook,
since it might be installed outside of $PATH.
Also, add uninstall hook to remove the binary catalog.
Some filesystem magics are too big to fit in 31 bits,
and are wrapped to negative. f_type is an int on 32 bits, so
it is signed, and we get a warning on comparison.
More specifically this adds a number of macros that resolve to
directories for udev rules, hwdb entries, tmpfiles and sysctl.
Thsi also includes three new macros for rebuilding the hwbd/catalog
index when a package drops in new files
This remove distro-specific support for early-boot SysV init scripts.
(And leaves support for normal SysV scripts untouched).
If distributions wish to continue to allow early-boot SysV scripts in
their distribution-specific way they should either maintain this patch
downstream manually, or write a generator for them, or simply ship all
those scripts with a .service wrapper.
We should always try to umount the old root dir if possible, instead of
overmounting it -- if that's possible.
The initial ("first") kernel rootfs can never be umounted, hence
for the usual nitrd case we never bothered using pivot_root() and
hence with fully unmounting it. However, fedup now tranisitions twice
during boot, and in that case it is highly desirable that the "second"
root dir is entirely unmounted when we switch to the "third". This patch
makes that possible.
The pivot_root() needs a directory in the "third" root dir, to move the
"second" root dir to. We use /mnt for that, under the assumption that
this directory is likely to exist, and is not itself a mount point.
If firmware file is not found in the file system, udev
terminates firmware loading. This is not the case if
firmware file exists in the file system but doesn't have
any data in it.
As it turns out reboot() doesn't actually imply a file system sync, but
only a disk sync. Accordingly, readd explicit sync() invocations
immediately before we invoke reboot().
This is much less dramatic than it might sounds as we umount all
disks/read-only remount them anyway before going down.
I'm building systemd for an embedded system and we would prefer not having
to include the entire util-linux package just to get a libblkid whose
functionality we don't need.
The message catalog can be used to attach short help texts to log lines,
keyed by their MESSAGE_ID= fields. This is useful to help the
administrator understand the context and cause of a message, find
possible solutions and find further related documentation.
Since this is keyed off MESSAGE_ID= this will only work for native
journal messages.
The message catalog supports i18n, and is useful to augment english
language system messages with explanations in the local language.
This commit only includes short explanatory messages for a few example
message IDs, we'll add more complete documentation for the relevant
systemd messages later on.

If ListUnitFiles fails, or an OOM occurs, then dbus_message_unref()
will be called twice on "reply", causing systemd to crash. So remove
the call to dbus_message_unref(); it is unnecessary because of
the cleanup attribute on "reply".
[zj: modified to leave one dbus_message_unref() alone, per Colin
Walters' comment.]
A service that only sets the scheduling policy to round-robin
fails to be started. This is because the cpu_sched_priority is
initialized to 0 and is not adjusted when the policy is changed.
Clamp the cpu_sched_priority when the scheduler policy is set. Use
the current policy to validate the new priority.
Change the manual page to state that the given range only applies
to the real-time scheduling policies.
Add a testcase that verifies this change:
$ make test-sched-prio; ./test-sched-prio
[test/sched_idle_bad.service:6] CPU scheduling priority is out of range, ignoring: 1
[test/sched_rr_bad.service:7] CPU scheduling priority is out of range, ignoring: 0
[test/sched_rr_bad.service:8] CPU scheduling priority is out of range, ignoring: 100
Having unit(s) removed/not started, even if it solved the issue and allowed
to boot successfully, should still be considered an error, as something
clearly isn't right.
This patch elevates the log message from warning to error, and adds a status
message to make things more obvious.
The point is to allow the use of journald functions by other binaries.
Before, journald code was split into multiple files (journald-*.[ch]),
but all those files all required functions from journald.c. And
journald.c has its own main(). Now, it is possible to link against
those functions, e.g. from test binaries.
This constitutes a fix for https://bugzilla.redhat.com/show_bug.cgi?id=872638.
The patch does the following:
1. rename journald.h to journald-server.h and move corresponding code
to journald-server.c.
2. add journald-server.c and other journald-*.c parts to
libsystemd-journal-internal.
3. remove journald-syslog.c from test_journal_syslog_SOURCES, since
it is now contained in libsystemd-journal-internal.
There are no code changes, apart from the removal of a few static's,
to allow function calls between files.
Supports Python versions 2.6 through 3.3 (tested on 2.7 and 3.2).
See JournalHandler docstring for usage details.
[zj: - use send() instead of using sendv() directly
- do exception handling like in the logging module
- bumped min version to python2.6, since the module
does not work with python2.5 anyway ]
Makes the output way nicer with shorter code. Also brings
systemd-analyze behaviour more in line with other systemd-programs.
Argparse is in Python since 2.6, and is available as a package for
previous versions, if someone is stuck with very old Python.
If a 'change' event is supposed to remove created symlinks, we create
a new device structure from the sysfs device and fill it with the list
of links, to compute the delta of the old and new list of links to apply.
If the device is already 'remove'd by the kernel though, udev fails to
create the device structure, so the links are not removed properly.

Use udev_device_new() instead of allowing udev_device_new_from_syspath()
to proceed without a sysfs device.
